f816395691 0029646: Boolean Operations algorithm produces a face with self-intersecting wire
Boolean operations - Allow repeated intersection of edges to find the coinciding pairs.
Previously, only the edges rejected by bounding boxes classification has been additionally checked on coincidence. The current patch removes this filter allowing all edges with coinciding vertices to be checked on coincidence.

Adjustment of the test cases for current behavior:
1. The following cases are improvements:
boolean volumemaker A8
bugs modalg_1 buc60703_1
bugs modalg_1 buc60703_2
bugs modalg_1 buc60703_4
bugs modalg_6 bug26789_1
bugs modalg_6 bug26789_2
bugs modalg_7 bug26883_4
bugs modalg_7 bug27948

2. bugs modalg_7 bug29580_1 is modified to extend the validity checks.

7f3408c8c8 0029580: Regression: invalid result of BOP Fuse
Boolean Operation - avoid creation of INTERNAL solid from unclassified faces in Solid Builder algorithm.
Instead warn the user that some of the faces have been unclassified and not used for solids creation.

Adjustment of the test cases.
Test cases for the issue.

32e849ebc9 0028486: Fuse of several solids fails due to presence of common zones between faces
1. Exception in intersection of two analytical faces has been fixed by adding a simple check on number of vertices
in the resulting analytical curve;

2. Projection of the Circle on the Cone now checks if the Circle's normal direction is parallel to the Cone direction.
If it is not, the different, more advanced, algorithm will be used for projection - ProjLib_ComputeApprox;

3. Intersection of the Edge with the Face (IntTools_EdgeFace algorithm) in QuickCoincidenceCheck mode has been fixed to
avoid the checking of the type of the intersection result if the coincidence check gives the positive result;

4. All common IN edges of the intersecting faces has been added for intersection with section edges to avoid self-intersection in the result;

5. Post treatment of the section edges in Boolean operations has been improved with the new stage which treats the possible
common zones, not detected by the intersection algorithm, between faces by intersecting each section edge with all faces,
not participated in its creation, and in case of coincidence putting it as IN edge into FaceInfo structure of the face.
The new function has been implemented for that - BOPAlgo_PaveFiller::PutSEInOtherFaces().

6. Checking for the SameDomain splits of faces in Boolean Operations has been modified to process the pairs of faces in
which both the section curves and common zones are present.

7. Adjustment of the test case boolean gdml_private ZH3 as improvement.

8. Test cases for the issue.

9. Test cases for the parent issue - 0026789.
